The system can automatically store the coordinate position of the defect, facilitates the analysis and processing of data afterwards, achieves the nondestructive detection of an automobile brake disc, avoids the missed detection probability of defective products, is simple in structure, is convenient in man-machine interaction operation, is quick in response, is free of electromagnetic radiation pollution, and is economical in cost.

Description

technical field [0001] The invention relates to the technical field of flaw detection, in particular to an STM32-based metal flaw detection system for automobile brake discs and a method thereof. Background technique [0002] The brake disc is a key component of the automobile braking system, and its quality directly affects the driving safety of passengers. At present, the quality inspection of brake discs mainly relies on microscopic metallographic method (destructive inspection) and sampling inspection. This will inevitably bring a certain probability of missed inspection of defective products, which will lead to major safety hazards. However, some non-destructive quality testing equipment for metal castings on the market are expensive, and some have electromagnetic radiation hazards, which are not suitable for product transformation and promotion. Contents of the invention [0003] The purpose of the present invention is to provide a metal flaw detection system and me...
